An unspecified JavaScript error before routine with slides

URL of experiment: ConsciousH [PsychoPy]

Description of the problem:
Hi everyone,
I have encountered an unspecified JavaScript error right before moving into a routine that contains multiple slides. There is not a single code component using in the whole psychopy file.
How come the error showed up?
Any suggestion would be appreciated. Thanks!

The most likely explanation is that you are using pixels as your units but you have text heights of less than .5 (suitable for height units).

Hi @wakecarter,
Thank you for replying. I changed the letter height in text component but it still showed up the same error when I tried to pilot.
Should I change other functions?
Thank you!
